Electronic cockroach, rodent and insect repeller: how does it work?

The main problem of summer residents and owners of private houses is the presence of various uninvited guests. At our dacha, we used various means, including folk options, to get rid of mice. They work, but only for a while. And during the winter, rodents feel safe. Therefore, it was decided to purchase an electronic version.

Ultrasonic pest repellents are electronic devices that emit high-frequency sounds, designed to scare away, injure or destroy household pests such as rodents and insects.

If left unchecked, rodents and insects can transmit salmonella, hantavirus and other diseases and cause significant damage to buildings. Signs of rodent infestation include droppings, especially near food and under shells, gnawed or chewed food bags, as well as holes in structural materials that can provide entry into the house.

Cockroach infestation, which is arguably the most common and intractable type of pest infestation, especially in urban areas and industrial and commercial kitchens. It is confirmed by pest droppings, commonly found in kitchen cabinets and hard-to-reach places such as cracks and crevices in kitchen cabinets and drains, as well as behind dishwashers and refrigerators.

How do they work

Using audible sound to contain pests is an old strategy; the ancient Chinese used a series of mechanically controlled sensory-repellant devices to prevent rodent infestation on crops and buildings. However, ultrasound, which is defined by sound frequencies outside the upper limit human hearing, has been used as a pest control agent only in recent several decades.

This device plugs into electrical outlets at home. Sound is thought to trigger a physiological response known as the audiogenic seizure response. which is characterized by non-directional running, convulsions and possibly death from hemorrhage in brain. The theory behind the devices is that confused rodents eventually flee when destruction prevents them from gathering food, breeding, building nests, or communicating.

Ultrasonic devices are popular and attractive to consumers due to their ease of use and the fact that they are silent to humans. hearing and is said to eliminate the need for traps and poisons, which some believe are inhumane forms of dealing with pests.

But along with all the positive qualities on the Internet, some users report that the sound can weaken clarity of telephone conversations, interfere with alarm systems and cause mute in hearing aids devices. Noise can also cause unintended disturbance to rabbits and pets such as guinea pigs and hamsters. Cats and dogs can hear in the ultrasonic range, but do not seem to be bothered by the noise emitted by these devices.

Devices should be placed in locations where their signals will pass without interruption from walls or furniture.
